Here is a detailed tutorial for Using Android binary package with Eclipse, and here is wiki page about samples. How to import OpenCV library project and samples If you want to understand how to use OpenCV in your Android application, do the following: Download the prebuilt package from
OpenCV, Computer vision for Google Summer of Code (GSoC) 2011 Object recognition with OpenCV, to be published in ICRA 2011 GSoC 2011 site Timeline for GSoC 2011 Next important dates: March 28: Students can begin to apply for GSoC2011 through Google's site April 8: You are now too late to apply, see you next year. . . . Internal discussion period . . . April 22: All mentors must be signed up by mid
OpenCV Installation Guide on Debian and Ubuntu Here you will get a step by step compilation guide for GNU/Linux Debian Squeeze and *Ubuntu. Why compiling ? You can not use the python-opencv package because he provide old python support (for more information, check this bug report.).On Ubuntu, python bindings won't work (check this bug report) So you must use the compilation. But there is also som
Using the Kinect Depth Camera with OpenCV This page is a starting point for learning how to use a Kinect RGB-D Depth Camera (originally for Microsoft's XBox 360) with OpenCV. Sam Muscroft has successfully incorporated the raw depth, rgb depth map and rgb output from the Kinect sensor into an OpenCV project using the Windows CL NUI Platform. RGB output as you'd expect is stored in an 8 bit 3 channe
Android Android is awesome, and so is OpenCV, so wouldn't it be awesomer if they could work together? Well they can, and its now officially supported in opencv trunk. quick ubuntu opencv static libs build install swig sudo apt-get install swig unzip the crystax ndk r4 to your home directory http://www.crystax.net/android/ndk-r4.php svn up your opencv - from https://code.ros.org/svn/opencv/trunk/o
Installation Of OpenCV 2.1 on Ubuntu Gijs Molenaar has build OpenCV 2.1 packages for Ubuntu Lucid and Karmic. You don't need to compile OpenCV anymore if you use these packages, except for when you want something special like enable IPP. Jaunty packages are also available but not updated anymore. To install OpenCV 2.1 on Ubuntu run these commands: $ sudo add-apt-repository ppa:gijzelaar/opencv2 $
Cookbook¶ Here is a collection of code fragments demonstrating some features of the OpenCV Python bindings. >>> import cv >>> im = cv.LoadImageM("building.jpg") >>> print type(im) <type 'cv.cvmat'> >>> cv.SaveImage("foo.png", im) Resize an image¶ To resize an image in OpenCV, create a destination image of the appropriate size, then call Resize . >>> import cv >>> original = cv.LoadImageM("building
Background information There are a lot of questions about video files on the OpenCV mailing list. Most of them were asked because of the still incomplete documentation of OpenCV, but also because many users don't know some background details of video coding. So this is a short primer to get you started. Video codecs and file containers It is a common misunderstanding to mix up codecs and containe

Installing OpenCV on Linux Here is brief description on how to build the latest version of OpenCV. See INSTALL file shipped with OpenCV for more detail. The required packages are listed below: GCC 4.x or later. In Ubuntu/Debian it can be installed with sudo apt-get install build-essentialCMake 2.6 or higher Subversion (SVN) client GTK+ 2.x or higher, including headers (e.g. libgtk2.0-dev) pkgconfi

Python Interface OpenCV has a built in python interface that utilizes SWIG to automate a large portion of the C -> python conversion code. This page documents API Differences in Python Using the Interface in an Interactive Shell IF ANYTHING ON THIS PAGE DOESN'T WORK AS YOU EXPECT, PLEASE REPORT A BUG. Note: see NoamLewis for info about using CTypes package with Open CV as an alternative to SWIG, t
OpenCV 2009.08 This is preliminary list of the features planned for OpenCV 2.0, the next major release of OpenCV, targeted for: 2.0 Beta, July 2009 Put out for feedback 2.0, August 2009. The goals in brief New C++ interface (with backward compatibility), Better Python interface with low-level capabilities. More 2D feature detectors and descriptors; Add 3D vision support: Better stereo support. 3D
OpenCV Installation Guide Common Prerequisities: C/C++ compiler (OpenCV is known to work with VS2005, VS2008, including Express Editions, and Mingw on Windows, GCC 4.x on Linux, MacOSX and other Unix-like systems). [Optional] Subversion client (e.g. command-line svn tool, SmartSVN, Tortoise SVN) [Optional] CMake 2.6 or later. CMake is now the only method of building OpenCV SVN snapshots on Windows

POSIT tutorial Pose Estimation JavierBarandiaran In this tutorial we will see how to estimate the pose of a 3d object in a single image using the function cvPOSIT. This function implements the POSIT algorithm (DeMenthon & Davis 1995). Also we will make some tests and see the result of the algorithm using OpenGL. The pose M of a 3d object is a combination of its orientation R (a 3d rotation matrix)
The OpenCV Coding Style Guide The source of this document is here. 1. Foreword The document is a short guide on code style, used in OpenCV. The core libraries (cv, cvaux) are written in C/C++, so the document concerns only the codes written in C/C++. 2. File Names All the file names of cv and cvaux libraries must obey the following rules: All the files of CV library have prefix cv. Mixed C/C++ i
Mac OS X OpenCV Port This page exists to track planning and progress on the Mac OS X OpenCV port. Development targets Mac OS X 10.4 (Tiger) and QuickTime 7 for the Mac-specific parts. Unix-like support (libpng etc., FFmpeg, GTK+) should be kept working for older systems. As a regular user, check out into a clean directory with: cvs -d:pserver:anonymous@opencvlibrary.cvs.sourceforge.net:/cvsroot/op
Blob extraction library A library to perform binary images connected component labelling. It also provides functions to manipulate, filter and extract results from the extracted blobs, see features section for more information. News 2008-08-24: Python binding for v6 released. 2007-03-22: Version v6 available for linux. Thanks to Jon Azpiazu. 2007-16-02: New version (v6) available! The performance

Face Detection using OpenCV How to compile and run the facedetect.c is one of the frequently asked question in the OpenCV Yahoo! Groups. I'll try to explain it to my best. Feel free to edit it if you have some more details.. Haar Like Features:What is that? A recognition process can be much more efficient if it is based on the detection of features that encode some information about the class to b
